Fire Suppression System

G, H, K, S and U Models Only

Water Requirements

IMPORTANT: Water must be supplied to the fire
suppression system, or the fire suppression system
will not operate as intended.

Connection point to the electric water solenoid valve is
a 19 mm (3/4 inch) hose. The fire suppression system
equipped tumbler must be supplied with a minimum
water pipe size of 12,7 mm (1/2 inch) and be provided
with a

minimum of 138 kPa (20 psi) and a maximum

of 827 kPa (120 psi) of pressure at all times. Flowrate
must be no less than, but approximately 57 liters
(15 gallons) per minute.

NOTE: Water pressure under 138 kPa (20 pounds
per square inch) will cause low flow and water
leakage at water solenoid valve.

IMPORTANT: Temperature of the water supply
must be kept between 4,4° and 48,9°C (40° and
120°F). If water in the supply line or water solenoid
valve freezes, the fire suppression system will not
operate.

IMPORTANT: If temperature sensors inside the
tumbler register a temperature below 4,4°C (40°F),
the fire suppression system control will lock out.
This feature protects against operation of the
tumbler with a possible frozen water supply. Only
when the temperature sensors register a
temperature above 4,4°C (40°F) will the machine
reset for operation.

IMPORTANT: Flexible supply line/coupling must
be used. Solenoid valve failure due to hard
plumbing connections will void the warranty. It is
recommended that a filter or strainer be installed
in the water supply line.

Water Connections

Figure 2

IMPORTANT: Thread hose couplings onto valve
connections finger tight, then turn 1/4 turn with
pliers. Do not cross thread or overtighten
couplings.

IMPORTANT: Replace all hoses every five years.

NOTE: Longer inlet hoses are available (as
optional equipment at extra cost) if the hoses
supplied with the tumbler are not long enough for
installation. Order hoses as follows:

Part No. 20617 Inlet hose 2.44 m (8 feet)
Part No. 20618 Inlet hose 3.05 m (10 feet)

Electrical Requirements

No independent external power source or supply
connection is necessary. Power to operate the 24 Volt
fire suppression system is from the rear junction/
contactor box.
